Industrial wire service is decided by three things: diameter consistency, purity and thermal behaviour. Changzhou DLX Alloy specializes in high-purity nickel products including NP1 and NP2 grade pure nickel wire. Our 0.025mm diameter nickel wire matches the quality of DKRNT NP2 0.025mm pure nickel wire, with Ni+Co content of 99.5% or higher (NP2) and 99.9% (NP1). Our pure nickel wire serves critical applications across multiple industries including aerospace and defense systems, medical equipment manufacturing, chemical processing, electronics production, food handling equipment and synthetic fiber manufacturing.
| Parameter | Value | Note |
|---|---|---|
| Diameter range | 0.025-10 mm | micro wire from 0.025 mm |
| Tolerance | Per drawing / ASTM B164 | exact values per drawing |
| Continuous length | Per order | dependent on diameter |
| Temper | Soft / hard / 1/2 hard | per drawing |
| Surface | Clean, oxide-free | per drawing |
MOQ: 1 kg for micro wire (≤0.05 mm); 5 kg for standard wire.
| Class | Diameter | Typical use |
|---|---|---|
| Micro wire | 0.025-0.05 mm | Fine electronics, precision components |
| Fine wire | 0.05-1.0 mm | Electronics, sensors, welding |
| Standard wire | 1.0-10 mm | Industrial and structural service |
The melting point of 1435-1446°C defines the upper service envelope, while the Curie temperature of 358°C marks the magnetic transition. Thermal conductivity of 70.2 W/m·K (Ni200) supports heat transfer in service. Together these anchors let engineers select wire for thermal duty with confidence — the same values the DLX datasheet carries.
| Diameter | Resistance per metre | Mass per metre | Note |
|---|---|---|---|
| 0.025 mm | ≈196 Ω/m | ≈0.0044 g/m | calculated |
| 0.5 mm | ≈0.49 Ω/m | ≈1.75 g/m | calculated |
| 1.0 mm | ≈0.12 Ω/m | ≈7.0 g/m | calculated |
Values calculated with stated assumptions — for reference only.
Wire is drawn to the specified diameter with tolerances locked per drawing, and diameter is inspected at final inspection. For micro wire down to 0.025 mm, process control matters most; DLX verifies dimensions per batch against the governing standard.
Wire is available in soft, hard and 1/2 hard tempers. Soft temper supports forming and winding; harder tempers provide stiffness where the wire must hold shape. The temper is confirmed against the application at order time.
| Grade | Ni Content | Best Application | Reference Price (FOB, USD/kg) |
